BRAKE-GEAR MOUNTING.

Application led J'nly 6,

'My invention relates to mountings or lhousings* for the gear mechanism which operates the brakes. of railway cars; the housings being of a construction adapted to e be secured to the end of a car either to the car end sill or to the end sill of the car underframe. I

The mounting preferably. consists of a pair of members so constructed and secured lo together that sutiicient strength and rigidity will be provided; easy assembly of the gear elements permitted and attachment to the car frame or underframe easily accomplished. e

AThe objectsand advantages of my invention will be readily comprehended from the detailed description of the accompanying drawings, wherein- Figurel is a top plan view of my improved mounting shown attached to the' end sill of a car; only a portion of the end sill and striking 'casting being shown with the brake-staff shown in section.

Figure 2 illustrates the same in elevation. Figure 3 is a cross sectional view talien on the oil-set line 3 -3 of Figure 1 looking in the direction of the arrows..4 l

Figure 4 is a perspective view ofthe top member of the mounting or housing. A Figure 5 is a perspective view of the bottom member of the mounting or housin Figure 6 is a side elevation of 1a modi cation of my improved housing and the method of mounting the same, namely ,ap-

lied to the end sill of a car underframe and raced`- from the end sill of the car body. Figure 7 is a top plan view thereof with portions ofthe sill of the car body and end sill lof the underframe; thelatten with the lo brake-stati being shown in section.

ln the exe plii'ication of the invention as illustrated in the first three figures of the drawings; my improved mounting-1s shown secured to the stifiening member or end sill te .-10 of a car body and located adjacent to the striking casting, 'a portion whereof is shown at 11. The mounting comprises a top member 12 and a bottom member 13, the general constructions whereof are more clearly 5o shown in Figures 4 and 5.

The top member 12 '.consists of a plate which may be substantially rectangular as shown, with the inner end 14 having a substantially flat upper surface to extend Hush with the bottom ange of the end sill 10 1926. Serial No. 120,570.

of the car body to which it is secured by means of rivets- 15; the portion 14 of the top plate being apertured at 16 to receive the rivets 15. The inner portion 14 of the top plate, as seen in Figure 3, not only extends flush with the bottom of the end sill of the car body, lbut also terminates adjacent to the inner end of the lower flange of the end sill member 10. lThe forward or outer end of the top plate 12 is shown preferably slightly offset or stepped downwardly at 17 in order to provide proper bearing for the short upper trunnion of the drive element or gear 18 which latter is controlled by the brake-statt' 19. The forward or outer end of the top plate 12 is apertured at 20 (see Figure 4). to receive the upwardly d isposed trunnion 21 ofthe drive element, see Figure 3; the drive element or gear being provided with a squared opening to receive steel end or outer sheathing 24, see Figure i 3; the upstanding wall 22 being' apertured as at 25, 25 to receive the rivets 26, 26 whereby the top plate is also secured to the upstanding leg of the car end-sill and the sheathing.

The forwardly extending portion or outer end of the top plate 12 is also shown provided with a suitable number of bolt or rivet-receiving holes 27 for the reception ofy or plate 13 is secured thereto.

The bottom member or plate 13 consists of the forward portion 29, of dimensions substantially e ual to the width of the forward outer en of top plate 12, see Fi re 5. This end 29 of bottom plate 13, w ich may be substantially rectangular, is 'provided with upstanding ends 30 and 31 which in turn terminate in the horizontally and inwardly disposed lobes 32, 33 apertured at the rivets 28 whereby the bottom member i'32 and 33a to register with the apertures 27 in the top plate 12. The inwardly dis-v posed lobes 32, 33 are intended to lie flush with the bottom of the forward end ,of the top plate 12, to which it is secured by the rivets l28. t

The portion 29 of the bottom plate 13 isA shown provided with an apertured boss 34 to receive the trunnion 35 on the lower side of the drive element or gear 18 so as not) intermediate of the ends of the rectangularA portion 29, namely at a point in alignment vwith the apertured boss portion 34, 1s pro'- -vided with an inwardly disposed arm 39 which is shown preferably o-set into a lower 'plane to .provide suitablepspace between\the\t`op and bottom members to house the driven element or gear 40 and the chain receiving drum or spool 41. The bottom member is preferably provided with the vertically disposed reenforcing ribs or webs 42 extendin4 throughout'the length of the bottom mem er.

The inwardly disposed end 39 of the bottom member is provided with an apertured -boss 43 to provide aseat for the drum or spool 41 an to receive the extended 4hub 44 of the gear 40. The gear and .drum or spool vare held in place by the pin 45, which also assists in supporting the inner end of the bottom plate 13. Y'

` The top plate or member 12, on its lower side, is shown provided with a boss46 apertured vto receive the pin and the top surface of the top plate 12 is countersunk at 47 to receive the head of the pin 45. This permits the top plate to extend flush with the bottom of the end sill. The pin 45 may be of any suitable construction; and while displacement of thepin or bolt 45' is impossible after the 'housing is in place, the lower end df the pin is shown threadedto receive a nut 48 in order to ensure the elements being held in assembled relation before the housing is mounted on the car; namely to prevent loss of the pin before installation.

In view of the housing being .secured to I the end sill ofthe car body and therefore adjacent to the striking castlng 11, the countersunk opening 47 in the top member or plate 12 is shown off-set from the opening 20 and the opening 43 in bottom member 13 off-set from opening 34, in order to provide properclearance for the large driven element or ear 40, relative lto lthe center sill and stri ing casting of the car, seeFigure 1.

In Figures and 7, I show a modification of the invention; the figures illustrating a mountin of the gear mechanism beneath and to t e bottom ange of the end sill 49 of the car underframe. v The construction'of. the main portion of the housing is substantially identical with that previously described; the housing consisting of the toppla'te 50 and bottom plate or'member 51 secured together as` previously described. The y 'upstanding flange or wall 55 disposed transversely of the top plate with the endsof thel flange or ribs sloping downwardly 2toward the outer corners of the forward vportion of the. top plate 50, see Figure 7. The. upstanding flange or wall is intended to, extend flush with theouter vertical face of Athe underframe end sill` 49. The mounting also involves a reenforcing brace or strap 56 preferably of the rectangular formation shown' in Figure 6, with one end disposed flush with the bottom of the car floor 57;

to which, as well as to-car end sill .10, it is secured as shown at 58. The other or lower portion or end ofthe brace plate or strap 56 is riveted to the top plate 50, as shown at 59,

and is bent upwardly to lap the lower flange j of the underframe end sill 49 as well as to extend flush with the inner vertical face thereof. This last mentioned end ofl the brace plate or strap 56 is riveted to the underframe end sill 49 by rivets 60 which also secure the'upstanding iange or wall 55 of the top plate to the end sill.

The .lower surface of the top plate is shown provided with a depending,` stop lug 6l. adapted to be engaged by a lug 62 formed on the driven element or gear 40. to ref vent improper rotationv of the driven e ement. y s v The constructions shown provide a gear mounting possessing the requisite strength while at the sametimebeing comparatively light. in weiffht; constructions which may bel easily assem led and installed on a car.-

The invention with its modification has limit-ation as structural modifications are V101s l been described in terms employed merely as terms of description and not as terms ofpossible without, however, departing from the spirit of my invention.`
